‘A living pantry’: how an urban food forest in Arizona became a model for climate action

A decades-old neighborhood project in Tucson provides food to residents as well as shade to cool streets in the third-fastest warming city in the US

Near downtown Tucson, Arizona, is Dunbar Spring, a neighborhood unlike any other in the city. The unpaved sidewalks are lined with native, food-bearing trees and shrubs fed by rainwater diverted from city streets. One single block has over 100 plant species, including native goji berries, desert ironwood with edamame-like seeds and chuparosa bushes with cucumber-flavored flowers.

This urban food forest - which began almost 30 years ago - provides food for residents and roughage for livestock, and the tree canopy also provides relief to residents in the third-fastest warming city in the nation. It has made Dunbar Spring a model for other areas grappling with increased heat, drought and food insecurity caused by the climate crisis.
